My report,
After brief flight testing in multiplayer.
1) FPS increase, especially on the ground (20-30 FPS), but stutters still occuring. (my res is 2560x1600).
2) 109 prop pitch change is much faster

3) The new multiplayer GUI is much easier to use, thanks!!!
4) the multiplayer sound bug, where sound starts to stutter and disappear is still a problem. Not fixed

5) 109 roll rate looks to have been increased.
Thats all for now. Cheers.
